- Analysis of the County’s Landscape Pattern in Loess Hilly Region
- 分类号:
- X171.1
- 摘要:
- 以景观生态学为研究方法，以GIS为技术支撑，选取景观多样性、优势度、均匀度、破碎度、分离度、分维度等指数，对黄土高原丘陵区方山县景观空间分布和结构特征进行了分析研究。结果表明：方山县斑块面积较大，斑块结构复杂；景观整体多样性较低，林地景观占较大优势，景观生态系统较不稳定。根据研究结果，对方山县现状及今后的发展提出建议。
- Abstract:
- Using the landscape methods, under the supporting of GIS techniques, the indices related to landscape diversity, dominance, evenness, fragmentation, isolation and fractal dimension are chosen. Then the structure and spatial distribution of landscape types are analyzed using these indices for Fangshan County. The results show that the average patch area is biggish, the patch shape is complex;the total variety of landscape in Fangshan is low and the forest land take high landscape proportion, and landscape ecosystem is very unstable. According to the research results, some sustainable developmental countermeasures are put forward.
